Trial Design

3Treatment groups
Experimental Treatment
Group I: Cohort C: Healthy Participants (Control)Experimental Treatment1 Intervention
Healthy participants matched to participants with hepatic impairment in Cohorts A and B (matched with regards to age, sex, body mass index \[BMI\]) will receive a single 10 mg dose (1 × 10 mg lemborexant \[E2006\] tablet) in the morning with 240 mL of water following an overnight fast of at least 10 hours.
Group II: Cohort B: Moderate Hepatic Impairment (Child Pugh Class B)Experimental Treatment1 Intervention
Participants with moderate hepatic impairment will receive a single 10 mg dose (1 × 10 mg lemborexant \[E2006\] tablet) in the morning with 240 mL of water following an overnight fast of at least 10 hours.
Group III: Cohort A: Mild Hepatic Impairment (Child Pugh Class A)Experimental Treatment1 Intervention
Participants with mild hepatic impairment will receive a single 10 milligram (mg) dose (1 × 10 mg lemborexant \[E2006\] tablet) in the morning with 240 milliliters (mL) of water following an overnight fast of at least 10 hours.
